Please help me for this example

Tell us what’s happening:

Your code so far


function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
  // Your code below this line
  var result ="myAdjective," +"myNoun," + "myVerb," +"myAdverb";

  // Your code above this line
  return result;
}

// Change the words here to test your function
wordBlanks("dog", "big", "ran", "quickly");
var result =""

A variable inside of “” is no longer a variable.

let name = "Bob";

console.log("name"); // logs name to console
console.log(name); // Logs Bob to the console

Your wordBlanks function returns the following string.

“myAdjective,myNoun,myVerb,myAdverb”

That sure does not look like a sentence and it definitely does not use any of the words passed into the function like “dog”, “big”, “ran”, or “quickly”.

Your result variable is returning strings.
You want there to reference the parameters from the function .

In your case “myAdjective” (this is a string) you want it just as

myAdjective

just a reference and not a string literal.
I am suggesting you to learn javascript types first.
